New exhaust manifold gasket needed?
 

Almost new engine, what just happened here? Did someone reuse an old exhaust manifold gasket?

Warped exhaust manifold flange?

Were the manifold nuts torqued down properly?

I had this problem so I installed a new gasket and the leak is gone. I think these are re-usable for street cars, not for people like us especially not that that runner is warped.

Already ordered a new gasket and will have the manifold machined.

Looks to me like it wasn't torqued down. Manifold is probably slightly warped as well.

Toss another gasket on there and sock it down.
